| <p>The Graphical Explorer of MPI Programs (GEM) Eclipse plug-in, part of the |
| <a href="PLUGINS_ROOT/org.eclipse.ptp.help/html/toc.html">Parallel Tools Platform</a> (PTP), |
| is a graphical front end for In-situ Partial Order (ISP), a dynamic formal |
| verification tool for MPI C/C++ programs, developed at the University of Utah. GEM |
| greatly enhances the usability of ISP by providing an intuitive graphical way to track down |
| bugs in MPI C/C++ programs, examine post-runtime results and to analyze MPI runtime |
| behavior. |
| </p> |
| |
| <p> |
| GEM can be used by anyone who can write simple MPI C/C++ programs, and requires no |
| special training. GEM allows you to formally verify your MPI C/C++ programs automatically |
| without any extra efforts on your part (apart from compiling and making your examples) |
| and flags the following errors: |
| </p> |
| |
| <ul> |
| <li>Deadlocks</li> |
| <li>Assertion violations</li> |
| <li>Object leaks</li> |
| </ul> |
| |
| <p> |
| In addition, GEM helps you understand as well as step through all relevant process interleavings |
| (schedules). Notice our use of the word <i>relevant</i>: even a short MPI program may have too many |
| (an "exponential number") of interleavings. For example, an MPI program with five processes, each |
| containing five MPI calls, can have well in excess of 1000 interleavings. However, ISP generates |
| a new interleaving only when it represents a truly new (as yet unexamined) behavior of your programs. |
